We have added a new program (<A NAME="tex2html352" HREF="../man/greenspline.c.html"><I><B>greenspline.c</B></I></A><A NAME="3858"></A>) which offers interpolation and gridding in 1-3 dimensions using Green's functions of various splines. Also, the <B>misc</B> supplement has a new tool (<A NAME="tex2html353" HREF="../man/gmtdp.c.html"><I><B>gmtdp.c</B></I></A><A NAME="3863"></A>) which offers line-reduction using the Douglas-Peucker algorithm we used for the various shoreline resolutions.
